Three review findings:
- The picker filtered every catalog member out of Recommended and Hub
search on the way to canonical group rows, but nothing renders those
rows yet (catalogGroupFitsDevice and groupMatchesQuery are imported and
unused). A task-scoped picker's models list is catalogToModelOptions(),
i.e. group members exclusively, so both lists came back empty and no
curated model could be discovered or downloaded. Keep the artifacts
listed until the grouped UI exists.
- The video delete guard compared only repo_id, so deleting the
companion base of a loaded GGUF video model was allowed even though it
supplies the VAE and text encoders. Compare base_repo too, matching
what the images guard already does for its companions.
- diffusers was declared unversioned while the diffusion stack requires
0.39 (Krea2Pipeline, the cache_context child registries, the Flux2 and
Z-Image pipelines), so an upgrade could keep an older release and
selecting an advertised model failed until the user upgraded by hand.
